If you've ever wanted to shine in the spotlight, try this tutorial. It shows you how to create a silhouette of a person taken from a normal photo, adding colorful light to it as if the light source is located behind this object.
Step 1
Start out by importing the image you want to cut the silhouette from into Photoshop. I used an image with a white background, which makes cutting very easy. Everyone has their own way of cutting something out, so I will not include that part in this tutorial. If you are unsure how to cut something out, look for a tutorial on that subject first.
When you are ready and feel like you have a clean cut, go into the layer's blending options, choose Color Overlay, and set the color to black. This should give you the silhouette of what you cut out. In my example, I did the hair separately and used a lower opacity on the Color Overlay so you can still see some gray tones.
